Treatment system

A team of several dentists with specialties, pre-graduate interns, and residents provides dental therapy. In addition, the department includes specialist and supervising dentists certified by the Japanese Society of Conservative Dentistry, Japan Prosthodontic Society, and Japanese Society of Periodontology.

Treatment policy

The plan of treatment of each patient is discussed by a primary dentist plus several dentists from each specialization, to provide evidence-based dental therapy. The treatment policy is not only to target disorders in stomatognathic systems, but also to provide widely various holistic treatments, keeping communication with patients in mind. Furthermore, we hope to contribute to systemic health as well as oral health through post-treatment maintenance and regular checks.


Generally, at a university hospital, a patient with several oral problems must visit different specialized departments for each treatment. However, the Comprehensive Dental Clinic enables a primary dentist to provide all treatments in cooperation with different specialists and thereby save the patient the trouble of changing departments for different procedures. In other words, our clinic can provide general treatment for all problems related to the mouth as a unit. Additionally, in cooperation with the specialized departments, it can treat problems that are judged to require advanced treatments.

Scope of Target diseases

  • Caries: decalcified tooth, with substantial deficiency; with symptoms of acute pain or pain.
  • Periodontal diseases: chronic inflammation caused by bacterial infection, possibly causing gum swelling, absorption of bone tissue around a tooth, and toothmobility.
  • Pulp inflammation/apical periodontitis: caries advancing to a nerve, possibly causing inflammation or acute or chronic periapical inflammation with pus caused by pulp death.
  • Tooth loss: by which a tooth is lost for some reason, necessitating a crown or artificial denture.
  • Pericoronitis of wisdom tooth: by which a wisdom tooth causes inflammation of the surrounding gum tissue.

In addition, all general diseases of the mouth are targeted.

You can make an appointment for the next time after your examination is over. You can change the appointment by calling the desk of theComprehensive Dental Clinic: 080-235-6787, 6788. In an emergency, you can receive treatment without an appointment. If you are a first-visit patient at first consultation, you cannot make an appointment, but must be referred.

Main methods for testing and investigation

  • Dental X-ray: x-ray photography can reveal the presence of caries, periodontal disease, apical periodontitis, or any disease surrounding a tooth.
  • Panoramic x-ray: used to ascertain the presence of any disease within the jawbone.
  • Oral photograph: used to judge the mouth condition objectively and confirm changes. Usually, 11 oral photographs are taken.
  • Periodontium examination: conducted to assess the progress of a periodontal disease.
  • Electric pulp test: used to ascertain the vital reaction of tooth nerves.

Furthermore, almost all examinations generally performed in the clinic can be conducted. Additionally, we provide a detailed explanation of the results to a patient and use them for drawing up treatment plans or methods.
